GAS- -STOVE.

SPECIFICATION forming part of Letters Patent No. 746,752, datecl'December 15, 1903.

Application filed January 8, 1903- Serial No 138,212. (No model) To all whom it may concern.-

Be it known that I, Louisstnvnntmma citizen of the United States, residing in the city, county, and State 05 New York, have invented aeertain new and useful Improvement in Gas-Stoves, of which the following is aspecification.

In using gas-stoves for heating rooms, halls, &c., it is desirable to have facilities whereby without changing the sizes of the flames at each gasejet different degrees of heat production may be obtained. 1 have devised a form of gas-stove adapted to permit the user to turn on or off one or more gas-jets Without interfering at all with the remainder, thus varying the heating efiect of the stoves.

My invention is illustrated in a preferred form in the accompanying drawings, where- 1n- Figure 1 is a plan view of one end of a stove employing my invention. side View of the same, the inlet-pipes being out off between theirvalves and the stove proper, and Fig. 3 is a sectional view on the line a; m of Fig. l.

In the stove shown the usual radiating drums or pipes 1 are mounted upon a base, which in my device is made in two parts, as plainly indicated in Fig; 3.

The lower base 2 is provided with the usual legs (shown at 3) and is open at the top, where it is surrounded by an edge or lip 4, over which fits and overlaps the lower open edge of the upper base 5. A shoulder 6 on the lower base supports the aforesaid lower edge of 5.

'Suitablymounted brackets 7 support a common inlet-pipe 8, from which there branch 0ft at intervals the shorter pipes 9, provided each with its separate cook or valve For this purpose- Fig. 2 is a 10. As shown in Figs. 2 and 3, each pipe 9 passes through the base of the burner at the junction of the upper and lower bases, there being provided a semicircular opening 11 in the upper base registering with a similar opening in the lower base and producing circular apertures for the various inlet-pipes.

As shown in Fig. 1, each pipe 8 is provided with branches 12 beneath the openings of the radiating drums or pipes 1, and these branches are provided with lava tips or other burners 13.

By the use of two bases, as shown, combined with pipes 8, passing through apertures formed by registering half-holes in the two bases, the whole device is the more quickly taken apart or put together, and the pipes are secured in place partly by the overlapping upper and lower bases.

By employing separate branch pipes 8, each with its own burner or set of burners and its own valve, the user can use all the burners to get up heat quickly in a room and then maintain this high temperature by the use of fewer of the burners, and this can be done without changing the flow of gas at any one burner, and consequently While preserving complete combustion and avoiding bad odors.

hat I claim is- In a gas-stove, a lower base having an upturned lip around the open top of the base and a shoulder surrounding said lip, in combination with an upper base having an open bottom the edge of which overlaps said lip on-the lower base and rests upon the said shoulder, substantially as described.
